Definitions

  • the invention relates to a device for knife conization of the cervix, with a band-shaped flexible knife which can be changed in position in the radial direction.
  • Knife conization of the cervix is a method for taking a tissue sample from the cervix to determine possible pathological changes and at the same time for the therapeutic elimination of pathological tissue on the cervix.
  • the knife In another known instrument for conization of the portio, the knife is rigidly held in a certain cone angle, so that the tissue sample to be removed is adapted to the individual in terms of its shape and size
  • the invention has for its object to provide a fully mechanized and largely automatically working device with which
  • OMPI Contrary to the known devices, histologically meaningful and thus therapeutically satisfactory tissue samples of individually determined cone shape and size can be obtained with regular certainty.
  • the knife conization as such should also be able to be used more frequently to really completely remove the tissue changes due to much easier handling.
  • the cervical canal can always be assumed during the procedure, in that first a radial incision movement is carried out from there, which at its outer end changes into a conical circular movement. In all cases, this enables comparatively symmetrical conical samples, which among other things prevents increased bleeding by cutting away more distant blood vessels. Because of the invention, the whole conization is also done particularly gently, because tugging and tearing movements are excluded. Due to the high-frequency caustic provided on one embodiment of the invention exclusively on the outside of the separating knife, the cut surface of the tissue part remaining in the patient's body can be sealed to prevent bleeding and a sample can nevertheless be obtained for examination, the cut surface of which in turn is not coagulated and thus histological can be properly evaluated.

  • FIGS. 10-14 represent a second exemplary embodiment of the knife configuring device, specifically this device is set up for electro-caustics by introducing electrical current into the knife sheath 62, for which purpose a current guide rail 72 is embedded in it, which is connected via a electrical line 73 is connected to a voltage source 74 (FIG. 10). From this voltage source, the electrical current is conducted via a line section 73a to the claw 58, in which the flange 56 rotatably engages.

  • the ball head 63 is conductively connected to the conductor rail 72, which has the shape of a narrow spring steel rail.
  • Their inclusion in the knife sheath 62 results in particular from FIG. 14, which shows a cross section through the sheath and knife.
  • the knife sheath which is U-shaped throughout, has a leg 62a in which the current guide rail 72 is located.
  • This leg 62a has an essentially unchanged cross-section over the entire length of the sheath 62, so that the conductor rail 72 is completely covered there and does not protrude outwards. As a result, no electrical contact can occur in the region of the sheath leg 62a with parts of body tissue along which the leg 62a moves.
  • the current guide rail 72 is provided with preferably integrally formed extension pieces 75, which are located at regular intervals on the current guide rail 72 (FIG. 13). These end pieces extend at right angles from the current conducting rail 72 and are also guided in a U-shape within the U-bend of the sheath 62 connecting the legs 62a, 62b and pass through the leg 62b in an embedded form up to its front edge, where they are freely conductive as contact 76 emerge.

  • the driver pin 68 touches the contact rail 80 during its intended movements during conization, the current is passed on via this pin and the tube 50 carrying the pin to the stylus rod 48. which carries near its tip a driver pin 81 which engages in an opening of the knife 61 and thereby causes its oscillating movements.
  • the second pole of the voltage source 74 is connected to the knife 61 and thus the bipolar system is produced. It is understood that the components connected to different poles must be insulated from one another.
  • the knife sheath 62 Due to the special design of the knife sheath 62 with its electrical contacts 76, 78, only the tissue remaining in the patient's body is caustically closed after the knife has been swung into the circular path, while the surface of the tissue of the conical sample remains unchanged, so that bleeding occurs on the one hand can be heavily contained, but on the other hand no impairment of the possibility of examining and assessing the removed tissue has to be accepted, as is the case with conventional electro-caustic the case is.
  • the described configuration leaves behind a caustically sealed wound crater with a smooth, regular surface, to which the crenellated design of the leg 62b of the knife sheath 62 also contributes, since this enables a very uniform bending of the entire knife organ.
  • the conductor rail 72 also takes on the task of a stabilizing element in the U cutting of the knife 61, which contributes to the quiet knife guidance during the conical cutting path E, so that any vibration influences on the part of the knife drive are switched off.
  • Vibrator (not shown) takes place, which allows the knife to oscillate at approximately 50 to 200 Hertz with a stroke of approximately 0.1 mm.
  • a rubber cushion (not shown) can be used as an abutment for the knife holder.
  • This drive has the advantage that the transmission shown in FIG. 1 can be partially omitted, which makes the device lighter in weight.

Abstract

Dispositif pour prelever un fragment de forme conique du tissu du col de la matrice, au moyen d'un couteau (61) en forme de ruban flexible. Ce couteau presente une extremite apte a etre introduite dans le canal (M) du col de la matrice et portant une tige coupante (48) pouvant accomplir un mouvement radial de va-et-vient. A l'autre extremite, le couteau presente un organe de retenue (65) s'etendant radialement depuis l'axe de la tige coupante, apte egalement a accomplir un mouvement axial de va-et-vient de pivotement radial et de torsion le long de son axe. De cette maniere, le couteau (61) execute d'abord un mouvement radial de coupure puis, a la fin de celui-ci, une trajectoire circulaire conique de facon a separer le fragment conique desire. Le couteau (61), a l'exception de son arete coupante, est entoure d'une gaine (62) en forme de manchon flexible en matiere synthetique. Pour l'electro cauterisation, un conducteur de courant (72) peut etre loge dans la gaine (62) et etre relie a une piece saillante (75) en contact avec le corps et agissant seulement sur le cote exterieur de la coupe, de facon a produire une thermo coagulation seulement sur la partie restante du tissu.
